SPINNING DEVICE.

lApplication led July 12, 1915.

To all whom 'it may concern Be it known that I, HENRY EVANS, a citizen of the UnitedStates, residing at Lewis; ton, in the co-unty of Androscoggin and State of Maine, have invented certain new and useful Improvements in Spinning Devices; and I do declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates broadly to improvements in spinning machines and mo-re particularly to those having a bobbin member and a thread guiding member for distributing the' thread thereon, the two being adapted to be rotated by the same means, but at different speeds, the guiding member being driven ata higher rate of speed than the bobbin member, whereby to wind the thread.

One object of the invention is to provide a speed checking device applied automatically to check the speed of the bobbin member, in case of rotation thereof at a speed equal to that o-f the thread guiding member, while an additional object is to improve upon the construction of the thread guiding members usually provided in connection with spinning machines of the class to which the invention relates.

Yet another Objectis the attainment o-f a simple yet highly eliicient and durable machine, which although possessing these and other advantageous characteristics willbe comparatively inexpensive.

With the foregoing objects in view, the invention resides in certain novel features of construction and the unique combinations of parts to be hereinafter claimed and fully described by reference to the accompanying drawings wherein: Y

Figures l and 2 are side elevations partly in section of a spinning device constructed in accordance with my invention, showingplied to use by actuation of the circuit closer; and, Fig. 6 is a detail side elevation Specification of Letters Patent.

ofthe locking device preferably used for retaining the spindle in its socket. Fig. 7 is a detail side elevation, partly in section showing the larger cap member for application to a comparatively large bobbin.

In these drawings which constitute a part of the application and in which like reference characters designate corresponding parts throughout the several views, l has reference to a suitable base commonly termed a bed rail, which carries a plurality of socket bearings 2, but one of these bearings being shown. Rotatably mounted in the bearing 2, is the lower end of the upright shaft or spindle 3, said spindle being provided with the usual driving pulley or whirl t which is disposed directly above the upper end of the bearing 2, and being longitud'inally grooved as seen at 5 from said whirl to a point substantially at its center.

Slidably mounted upon the spindle 3 and having an appropriate key traveling in the groove 5 thereof is an upright cylindrical bearing member 6 having ball races in its periphery which receive therein a lower series 7 and an upper series 8 of ball bearings, the series 7 being likewise disposed in a race in a bearing 9 which is carried by the vertically movable traveling rail 10 which may be of any preferred construction, open ated by any suitable mechanism forming no part of the present invention. Thus it will be evident that as the rail 10 is shifted as hereinafter delined, the bearing member 6 will travel therewith and will be rotated at the speed of the spindle 3.

The series 8 of ball bearings is partially confined in a race formed internally of an annular iange 1l which depends from a horizontally disposed base plate l2, this plate being provided at its center with an upstanding split sleeve 13 which surrounds and contacts lightly with the spindle 3, said sleeve receiving thereon the bobbin 14 when the machine is in'operation. By this arrangement of parts, when the spindle 3 is rotated at a high speed, the existing friction between Ysaid spindle and the split sleeve 13 will be suthcient to rotate the latter, but it will be driven at a speed slower than that at which the spindle is traveling, these relative speeds being essential in order that winding of the thread upon the bobbin may take place in the manner hereinafter set forth.

Surrounding the upper end portion of the spindle 3 and spaced therefrom a considerable distance, is a tubular cap member 15 having an open outwardly flared lower end 16 while its upper end is closed by a solid wall 17 from which a sleeve 18 depends, the latter receiving therein and being rigidly secured to the reduced upper end 19 of the spindle 3, whereby as the latter rotates the cap member 15 will be driven at precisely the same speed. The end wall 17 is provided therein with an orifice or guide eye-20 which leads from the center of its upper end to the periphery of the cap member 15, while at its lower end, said cap member is provided with an additional orifice 21 which leads from its periphery to its interior. In use, the thread 22 is passed through the orifice 20, is coiled a number of times around the cap member 15, and is then passed through the orifice 21 and initially wound upon the conical lower end of the bobbin 14 as shown in Fig. 1, which bobbin is then conned in the cap member 15. YVhen the device is now run under power rotation of the cap member 15 will so twist the thread as to cause the numerous strands thereof to closely contact with each other, after which such thread is wound upon the bobbin 14 which is traveling at a speed less than that of the cap member as before stated. During the winding operation, the traveling rail 10 is continually shifted gradually downward and then gradually upward the length of the conical lower end of the bobbin, and upon each up and down movement, the rail is moved downwardly the width of the thread, thus winding the entire bobbin as shown in Fig. 2.

Fig. 7 discloses a cap member 15 of larger size for application to larger bobbins, the results being the same. It is to be understood that the member 15 may be made of numerous dimensions according to requirements. vIt often happens that the bobbin 14 and the cap member 15, instead of traveling at different speeds, travel at the same speed, and under such circumstances no winding takes place. It therefore becomes highly expedient to provide a speed checking device applied automatically to check the speed of the bobbin 14, in case of rotation thereof at a speed equal to that of the cap member 15. To this end, the flange 11 of the bobbin carrying sleeve 13 is provided on its exterior with an annular braking surface, and pivoted to a boss 23 rising from the bearing 9,

and adapted to be forced into contact with said braking surface, is a brake lever 24. This lever has one of its ends bent laterally in one direction and provided with a curved seat 25, conforming to the curvature of the flange 11, with which it is to be forced into contact, while the other end 26 of said lever is bent laterally in the opposite direction and disposed adjacent an electro-magnet 27 the circuit of which is completed by a circuit closing device 28 when the bobbin 14 travels at the speed of the cap member 15. rlhe circuit closing device 28 may probably be actuated in any one of a number of different ways, and may well be of various designs,

but it is preferably spaced laterally from the cap member at the same speed, the threadr is loosened andthe weight 32 descends upon the contact 33, thereby completing the circuit of the magnet 27 and applying the brake lever 24 to again reduce the speed of the bobbin. This having been done winding again takes place but in case the bobbin again increases in speed to such an extent as to prevent winding of the thread, the brake will be again automatically applied as will be readily understood without requiring a more extended explanation.'

Preferably employed in connection with the features above described, although capable of application to use upon spindles of other constructions is the device 40 used for preventing dislocation of the whirl and spindle during operation, such device comprising a pivotally mounted shoe 41 which normally overlies an annular flange 42 on the whirl but which may be disposed out of contact with said flange to allow'the entire spindle and the whirl carried thereby to be removed. For so shifting the shoe 41, it is preferably provided with a segmental gear 43 which intermeshes with a similar gear 44 on a lever 45 which is fulcrumed to ears or the like projecting laterally from the bed rail 1, said lever being so actuated by a spring 46 as to normally prevent disposition of the shoe 41 to active position, it being evident, however, that said spring will yield ulflhen the lever 45 is actuated to apply said s oe.

The device 40 not only acts in the manner ljust described, but by actuation of the lever 45 in the proper direction, the shoe 41 may be vforced into binding frictional contact with the flange 42, thus serving to quicklycheck the speed of the spindle after the driv-v ing power thereof has been released.

From the foregoing description, taken in connection with the accompanying, drawings, the constructionV andthe manner of operation of the invention will be readily understood by those skilled in the art to which the invention relates, and further description or exposition is therefore deemed superfluous.

In the drawings, certain specic details of construction have been shown for accomplishing probably the best results, and in the foregoing, such details have been described, but it will be evident that I need not be restricted thereto otherwise than to the extent to which the appended claims limit me.

I claim:

l. In a spinning device, the combination of a leading and a lagging member, one carrying a bobbin upon which thread may be wound only when the two members travel at different speeds, slack in the thread being caused when said members move at the same speed, an electric brake for momentary application to the lagging member at intervals, and an electric circuit for said brake including a circuit closer comprising a fixed contact having connection with one wire of the circuit, and a movable contact having connection with another wire of said circuit and held normally from engagement with said fixed contact but in close proximity thereto by the thread, whereby if the leading and lagging members travel at the same speed and thus cause slack in the thread, the movable contact will immediately engage the fixed contact and will thereby complete the circuit of the brake to momentarily apply the latter to the lagging member.

2. In a spinning device, the combina-tion of a leading and a lagging member, one carrying a bobbin upon which thread may be wound only when the two members travel at diiferent speeds, slack in the thread being caused when said members move at the same speed, an electric brake for momentary application to the lagging member at intervals and an electric circuit for said brake including a circuit closer comprising a fixed contact having connection with one wire of the circuit, and a movable gravity lowered contact having connection with another wire of said circuit, said movable contact being disposed above and in close proximity to the other contact and having an eye through which the thread passes, whereby if the leading and lagging members travel at the same speed and thus cause slack in the thread, the movable contact will immediately engage the fixed contact and will thereby complete the circuit of the brake to momentarily apply the latter to the lagging member.

3. In a spinning device, the combination of' a leading and a lagging member, one carrying a bobbin upon which thread may be wound only when the two members travel at different speeds, slack in the thread being caused when said members move at the same speed, an electric brake for momentary application to the lagging member at intervals, and an electric circuit for said brake including a circuit closer comprising a fixed contact having connection with one wire of the circuit, a fixed support labove said fixed contact, a vertically slidable blade carried by said support and having at its lower end a weighted contact having connection with another wire of the circuit and positioned immediately above the aforesaid contact, and an eye at the upper end of the blade receiving the thread, whereby if the leading and lagging members travel at the same speed and thus cause slack in the thread, the weighted contact will drop by gravity into engagement with the fixed contact and will thereby close the circuit of the brake to apply the latter to the lagging member.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
